Masuda said in a 2013 interview that they thought the whole thing was too convoluted and confusing, so they decided not to distribute the flute.
>NWR: How come the Azure Flute was never made available in Diamond/Pearl/Platinum?>JM: When we were first developing the games we thought about including it. I thought it would be fun. But once the game was complete and released, I changed my mind down the road and didn’t think it would be – I thought it would be confusing for people and kind of hard to understand how it worked. So I eventually made the decision not to distribute it.For the record: you were supposed to beat the E4 and get the national dex, get the flute from the deliveryman at the Pokemon Center, go to the Spear Pillar at the top of Mt. Coronet, which prompts the player to use the flute, revealing the Hall of Origin.
